Begin by cooking the rice noodles according to package instructions. Typically, they need about 5-7 minutes in boiling water. Drain and set aside.
In a large skillet, heat olive oil over medium heat. Add the red bell pepper and snap peas, stirring frequently, and sauté for about 3-4 minutes until just tender.
Stir in the red curry paste, ensuring it coats the vegetables well. Cook for an additional minute until the curry fragrant is released.
Pour in the coconut milk, stirring to combine. Let the mixture simmer for about 5 minutes, allowing it to thicken slightly.
Add the cooked rice noodles to the skillet, tossing them gently to incorporate them with the coconut curry sauce.
Drizzle in the soy sauce and lime juice, then season with salt and pepper to taste. Mix everything thoroughly until heated through.
Remove from heat and fold in chopped green onions.
Serve the noodles in bowls, garnishing each with fresh cilantro and a sprinkle of crushed peanuts, if desired.
